Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To enhance the service utilizing information relating to programs by demultiplexing immediately a program reproduced from a recording reproducing means that records the program in a multiplexed digital signal and decoding and displaying the program. SOLUTION: A digital signal obtained by applying error correction to an input signal is given to a 1st demultiplexer section 404 via switches 414, 424. The 1st demultiplexer section 404 demultiplexes desired program information. In the case of recording a signal to a recording and reproducing means 423, a switch 414 is switched to connect an FEC 403 and a 2nd demultiplexer section 413 under the control from a control means 409. The 2nd demultiplexer section 413 extracts only data by which a viewer reproduces only a desired program at reproduction after the recording. Thus, even when an information amount of the received signal differs from an information amount recordable in the recording and reproducing device, only digital signals relating to the desired program are selectively recorded.

Title: Picture processing system
Inventor: SAKAI MASAKI
IPC: H04N5/91
Filed: 1989-12-29
Abstract: PURPOSE:To effectively use a storage medium in which information including many things is mixed and which can store information by forming reproduction information as a visual image when the attribute of reproduced information is that of picture information and forming picture information which an information generation means generates as the visual image when the attribute of reproduced information is the other attribute. CONSTITUTION:A picture storage device 3 quantizes a read digital picture from a color reader 1 and an analog video signal from an SV recording and reproducing unit 31, converts them into a digital picture and stores it. The SV recording and reproducing unit 31 reproduces picture information which an SV camera photographs and which is stored in a floppy disk and outputs it as the analog video signal. When information stored in the recording medium is picture information, the picture information is directly outputted. When it is sound or a digital signal, the image showing the content of information is formed. Thus, it can be eliminated that an unnecessary image is formed as against information except for picture information, and confusion at the time of storing and mixing information including many things. Then, the effective use of such kind of the storage medium can be prompted.

Abstract: PURPOSE:To make the falling amount of toner constant and to form the toner image corresponding to an image signal by rotating a toner supply roller in the state in contact with a toner control means and applying vibration to the toner control means to appropriately disintegrate a toner lump into individual toner particles. CONSTITUTION:The toner in a toner receiving container 10 is supplied to the first mesh member 23 of a toner control means 20 by the rotation of a toner supply roller 12. Since the toner control means 20 is rotated while the toner supply roller 12 is in contact with the toner control means 20 under pressure, vibration is generated and the toner lump is appropriately disintegrated on the first mesh member 23 to efficiently pass through the mesh parts of the mesh member. The toner particles pass through the first mesh member 23 and an electric field is generated in the toner passing holes 22 of a conductive substrate 21 by the electric signal applied to the second mesh member 25. The toner particles preliminarily charged negatively are attracted to the positive electric field applied to the second mesh member 25 as an image signal and pass through the second mesh member 25 to fall on the recording paper 60 placed on a base electrode 50 and the toner image faithful to the image signal can be always formed.
